SPOOL. OR BOBBIN.

SPECIFICATION forming part of Letters Patent No. 350,985, dated October 19, 1886.

Application tiled June *21, '1886.

To LZZ whom, it may concer/t:

Be it known that I, FRANK. M. Manci', a citizen of the United States, residing at lVorcester, in the county of Vorcestcr and State of Massachusetts, have invented certain new and useful Improvements in Spools or Bobbins; and I do hereby declare the following to be a full, clear, and exact description ot' my invention.

Heretofore spools have been made of wood, and after being iu use sometime the heads are liable to become detached from the barrel ot' the spool, or to check or crack, and in winding the thread gets into the cracks in the heads and breaks and causes more or less inconvenience.

To obviate these di ftieulties, I make the heads of my spools ot' metal and suitably fasten them to the wooden barrel ot' the spool.

In order that my invention may be fully understood, I will proceed to describe it with the aid of the accompanying drawings, in which- Figure l represents a central section of a circular metallic head, A, with a circular hole, A, in the center ofthe head A, and the outer edge ofthe hea-d A turned at right angles or more or less to the surface of the head A forming the lip A.

Fig. 2 represents a metallic tube, D, of suilieient length, with the diameter ol' the said tube B enough greater to allow one end to be cut down to the size of the hole A in the center of the head A, Fig. l, forming the shoulder E on the lube IE at a distance from the end of the tube D to allow the said end ofthe tube B to project a suliicient distance through the hole A in the head A, Fig. I, and the other end ot' the tube D is turned inward, forming the tlange B. I now take the tube I3 and drive the end having the shoulder E through the circular holcAin the circular` head A, Fig. l, until the head A is trmly set against the shoulder E. I then turn outward the part ot' the tube B projecting through the hole A in the head A firmly against the surface of the head A, as shown in Fig. 3, forming the flange B on the tube B, thus preventing the head A from drawing oft.

Fig. 8 represents the metallic head A, with the circular hole A in the center of the head A, the lip A, formed on the outer edge of the head A, and the tube B driven into the hole A in the head A up to the shoulder E on Serial No. 205,?27. (No model.)

the tube lll, and the flange D turned outward against the surface of the head A, and the flange D turned inward 'on the other end ot' the tube I3.

Fig. -t represents thel barrel C of the spool, of wood, and at each end enlarged the hole x, ruiming' the entire length of the barrel C to the outside diameter and to the depth ot' the length ofthe tube B, forming the hole C, so the tube Il will be a tight lit when driven into the holc C. I now make another hole, C, at the base cf the hole C', of a diameter equal, or nearly so, to the diameter ofthe space left at the end of thc tube B, Fig. 2, that has the tlange B,

said hole C to be of a sutlicient depth.

Fig. 5 represents the plug D, made of wood, with the hole x running through it, with the diameter of one part ot' said plug D to be of the diameter ot'v the inside of the tube Il, and the length of the plug D of this diameter to be the length ot` the outside of the tube B, and the diameter of the balance of the plug D to be the same as the diameter of hole C, Fig. 4. At'ter covering the outside surface of the tube as it is left at Fig. 3 with a cement, I drive it firmly into the hole C in the barrel C till the end ot' the barrel Crcstsiirmly against the head A, then cover the entire outside of the plug l) with a cement and force it into the inside ot the tube l till the end Vol` the plug D is flush with the surface, or nearly so, of the head A, and by this means the ilange B of the tube B is forced into the space on the plug D, where the two diameters come together, and the part ofthe plug D having the smaller diameter is vforced into the hole C of the barrel C, thus firmly histening the metallic head A to the wooden barrel C, as shown in Fig. (3.

Having fully described my invention, what I desire to claim and secure Letters Iatcnt on 1s- In a spool or bobbin, the combination ofthe metallic head A, having the lip A, the metallictubeB, having the shoulder E and flanges B and D, the wooden plugl D, and the wooden barrel C, all substantially as shown and described.

FRANK M. MAROY.
